A compound of formula (I), wherein, n is 0 or 1; R6 and R7 are h ydrogen, or together form a carbonyl oxygen; R1 is selected from the group consisting of hydrogen; -N(Z)Y and -C(Z)Y wherein; When R1 is -N(Z)Y, then: Y is selected from hydrogen, or the following, where G denotes the point of connection to the nitrogen atom in N(Y)Z (i-v); Z is selected from hydrogen or X1; Q is selected from hydrogen or W; The groups W are independently selected from th e group consisting of alkyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, arylalkyl and heteroarylalkyl of 1 to 20 atoms , The groups X1 are independently selected from the group consisting of alkyl, alkenyl, alkynyl, heteroalkyl, acyl, arylacyl, heteroarylacyl, aryl, heteroaryl, arylalkyl and heteroarylalkyl of 1 to 20 atoms , When R1 is -C(Z)Y, then: Y is selected fr om the group consisting of two hydrogen atoms, a double bonded oxygen (&equ als;O) to form a carbonyl, and a triple bonded nitrogen to form a nitrile, Z is absent, or is selected from hydrogen or U, Wherein U is selected from the group consisting of alkyl, alkenyl, alkynyl, heteroalkyl, aminoalkyl, aminoaryl, aryloxy, alkoxy, heteroaryloxy, aminoaryl, aminoheteroaryl, thioalkyl, thioaryl or thioheteroaryl, acyl, arylacyl, heteroarylacyl, aryl, heteroaryl, arylalkyl and heteroarylalkyl of 1 to 20 atoms, . When R1 is H, at least two of the groups R2, R3, R4 and R5 are selected from the group consisting of -OX2 or -N(T)Y, and the others are independently selected from hydrogen, -OH, -OX2, -N(T)Y, wherein Y is as defined above, T is selected fr om hydrogen or X2; and X2 is independently selected from alkyl, alkenyl, alkyny l, heteroalkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl of 1 to 20 atoms , When R1 is N(Z)Y or C(Z)Y, at least one of the groups R2, R3, R4 and R5 are selected from the group consisting of -OX2 or -N(T)Y, and the others are independently selected from hydrogen, -OH, -OX2, -N(T)Y, wherein Y is as defined above, T is selected from hydrogen or X2; and X2 is independently selected from alkyl, alkenyl, alkynyl, heteroalkyl, aryl, heteroaryl, arylalkyl or heteroarylalkyl of 1 to 20 atoms.
